Which map background color (white, black, other?) is best from the perspective of ergonomics at the workplace? Certainly aspects play a role such as reflections, tiredness of the eyes, contrast and others.
Here are to be considered only maps with point and line symbols. No polygons, no raster.
(Perhaps the question seems unusual from the perspective of some GIS users: The hardcopy (paper) has a white background and therefore they also use a monitor with a white background. However, there are GIS which provide an easy change of the background color and the color of the map symbols. It can easily switched between the colors for the monitor and the colors for print.)
The optimal color certainly depends also from various conditions. For example, this could apply here:
- TFT (no cathode ray tube)
- Work in the office (not mobile)
- Most of the time user collect data on the screen. But he must also read paper documents. Hence he switches from time to time between monitor and paper.
I would be happy to get answer with reasons/explanations. I think that there must be some objective reasons for the choice of color so that this is not a subjective question ("I like color x"). Our CAD staff says “black is best for eyes”. But they cannot explain why. (I suspect that 20 years ago (cathode ray tube) black was better).
Question is about best background color for a digital map on screen. Not for a printed map on paper.
